BD’s design achieves up to 80% higher clutch apply pressures over the stock unit and up to 50% over the competitors with the increase starting at much lower engine rpm’s and at lighter throttle pedal position movement. Light throttle shift firmness is also maintained at these higher apply pressures. This building process also eliminates the often referred to “Shuttle Shifting” or hunting-for-gears in the 2004-2006 48RE transmissions.

For exhaust brake usage, the higher pressures achieved by BD Valve Bodies help assist in preventing convertor lock-up clutch slippage. Second gear lock-up capability has also been added that along with the addition of one of our TorqLoc or AutoLoc kits, you can get some serious engine retarding capability on towing applications.
